Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.1K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Psychological and Sociocultural Causes of Schizophrenia

223
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Schizophrenia

288
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Psychosis and Antipsychotic Drugs: Overview

522
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Positive Symptoms Schizophrenia: Hallucinations and Delusions

154
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Psychosis: Goals of Pharmacotherapy

254
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Area of Science:

  • Neuroscience
  • Stem Cell Biology
  • Psychiatry

Background:

  • Human induced pluripotent stem cell (iPSC)-derived neural models have been utilized for over a decade in schizophrenia research.
  • These models provide in vitro neurobiological data but translation to clinical pathophysiology remains a challenge.
  • The gap between in vitro findings and the clinical presentation of schizophrenia persists due to the complexities of modeling brain function.

Purpose of the Study:

  • To review reproducible findings and emerging trends in recent schizophrenia-related iPSC studies.
  • To illuminate the relevance of iPSC study results in the context of human brain development.
  • To focus on developmental processes coinciding with critical periods for schizophrenia.

Main Methods:

  • Review of recent schizophrenia-related human induced pluripotent stem cell (iPSC) studies.
  • Analysis of reproducible findings and emerging trends.
  • Contextualization of results within human brain development.

Main Results:

  • Substantial in vitro neurobiological data has been generated from iPSC-derived neural models.
  • Translation of these findings into mechanistic concepts for schizophrenia pathophysiology is lagging.
  • The relevance of iPSC findings to human brain development, particularly during critical periods, is being illuminated.

Conclusions:

  • Schizophrenia research using iPSC-derived neural models has yielded significant in vitro data.
  • Bridging the gap between these models and clinical schizophrenia requires further investigation into developmental relevance.
  • Emerging trends highlight the importance of considering human brain development in iPSC-based schizophrenia research.
